Peer Discussion 1: A. Watt
The peer discussion by Watt took into consideration eight steps to take when faced with an unfamiliar database, and it included first identifying the variables and arranging them from the smallest to the largest. Then the student would determine the range of data, learn the measure of location with the median, mean, and mode, and then find the quartile range. The fifth step, according to Watt, is to ascertain the presence of any outliners and then to put the data into a few different graphs to establish the trends. Finally, the data is then presented in a figure that may be a dot plot, box plot, histogram, or a pie chart. However, according to Simpson (2015), the right procedure to follow includes the creation of an entity-relationship diagram, examine each table and column, determine the relationship between variables, view the triggers, read the stored procedures, and finally go through the application codes that are used in the database.
Peer Discussion 2: A. Mashruwala
In the peer discussion, Mashruwala outlined three significant steps to analyze the unfamiliar database of which I found to be more detailed. The first step is to gather information where an individual seeks to understand the origin of the data and what it represents. Also, the gathering of the report presents the source of the data and how it is generally shown. The second step is to organize the data such that the data is there is a distinction between the dependent and independent variables; also, the data should be held in order of their magnitude and group data. The third step is to analyze the data by calculating the descriptive statistics, plotting the graph, and adds additional forms of presentation such as pictures. Nevertheless, Evans (2014) adds that people should not always assume that the change in the null hypothesis is true until proven wrong. Once the hypothesis of the data has been accessed, the variables are then used to deduce how they relate.
